Consider the following demand schedule for shoes. Price Quantity Demanded $5 385 $10 365 $15 345 $20 325 $25 305 $30 285 $35 265 $40 245 10. Suppose that the store increases the price of shoes from $25 to $30. Using the mid-point approach, calculate price elasticity of demanded.

11. Suppose that the store increases the price of shoes from $25 to $30. Based on this information, the demand curve would be classified as (select one):
a. inelastic
b. elastic
c. unit elastic

12. Suppose that when the price of laundry detergent decreases from $4.10 to $3.50, quantity supplied decreases from 260 to 180.

Using the mid-point elasticity approach, calculate price elasticity of supply.
